Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Conclusion on classification
BC 001:
The substance is not classified according to GHS EU (Regulation (EC) No 1272/2008) for environmental hazards. The substance is poorly biodegradable and constituents are expected to have a bioaccumulation potential (BCF > 500). Daphnia are identified as the most sensitive organism in acute tests on aquatic toxicity. However, a long-term toxicity test with Daphnia is available and the EC10 reproduction was determined as > 1mg/L, the NOEC in the algae study was > 1mg/L. Therefore, the criteria for environmental classification according to GHS EU (Regulation (EC) No 1272/2008 are not fulfilled.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
